Of course we all know who's running for president by now (except maybe some of the third party candidates). If you don't know who's running locally you can find your candidates easily using the form listed on VoteSmart.org. The only problem I found with it was that it couldn't determine your school district, so it listed ALL the districts. Your school district is listed on your voter registration card or you can find it at Who Represents Me.

A few places to to do research on the candidates:
WacoTrib Election Page
Dallas Morning News Election Guide
(Good for Waco too, because you submit your address to find your candidates).
Project Vote Smart
Free Voters Guide
Fact Check Sites:
These sites help you fact-check candidates statements. I suggest reading the full articles if you have time since this gives you a really good understanding of the issues. While these tend to focus on presidential and congressional candidates, you can occassionally find articles on local candidates.
